The invention provides a living body detection method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a first detection video corresponding to a to-be-detected object; obtaining a plurality of first to-be-detected images from the first detection video, and determining an initial image feature of each first to-be-detected image, wherein the initial image feature comprises an image feature of the first to-be-detected image in a depth dimension; according to an image sequence of the plurality of first to-be-detected images in the first detection video, combining the initial image features of each first to-be-detected image to obtain a target image feature; and based on the target image features, determining a living body detection result of the to-be-detected object in the first detection video. According to the embodiment of the invention, the to-be-detected object in the first to-be-detected image is detected based on the target image feature obtained by combining the plurality of initial image features, so that the accuracy of the determined living body detection result is improved.
Description
technical field [0001] The present disclosure relates to the technical field of living body detection and image processing, in particular, to a living body detection method, device, computer equipment and storage medium. Background technique [0002] The wide application of face recognition technology has greatly facilitated people's lives, but at the same time, various attack methods against face recognition technology have begun to appear, and various face forgery methods have affected the recognition results of face recognition, such as , use photo remakes, 3D masks, etc. to imitate real human faces to pass face recognition. [0003] However, in the prior art, it is difficult to effectively deal with the above-mentioned attack methods, resulting in a problem that the accuracy of face recognition is not high. Contents of the invention [0004] Embodiments of the present disclosure at least provide a living body detection method, device, computer equipment, and storage m...
